✓Well SupportedStearic acid ingestion increases circulating C18 triglycerides and activates mitochondrial beta-oxidation.✓Well SupportedThe conversion of ALA to EPA and DHA is inefficient, especially in post-menopausal women and individuals with certain gene polymorphisms.✓Well SupportedIf an individual is thriving, no dietary changes are necessary; if not thriving, question dietary assumptions and continue learning.✓Well SupportedPasture-raised egg yolks, animal fats (butter, tallow, ghee), and the fat in grass-fed steak contain significant amounts of utilizable omega-3 fatty acids.Not Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Pescetarian diets can be a source of heavy metal toxicity due to high fish consumption.

✓Well SupportedEPA and DHA can be obtained from egg yolks, and ALA can be converted to DHA when linoleic acid from seed oils is not in excess.

✓Well SupportedAnimal fats like tallow and ghee, containing stearic acid and odd-chain fatty acids, activate mitochondria and fat burning, promoting leanness.

✕Not SupportedFish oil is susceptible to oxidation, and the body can obtain sufficient amounts from meat without needing to supplement.

✕Not SupportedHigh intake of fish oil supplementation may lead to increased lipid peroxidation.

✓Well SupportedPaul Saladino's lipid panel shows high DPA, DHA, and EPA, with low linoleic acid, despite not eating egg yolks, fish, or supplementing with fish oil.

✓Well SupportedVegetarians may benefit from consuming meat or tallow to obtain sufficient essential fatty acids.

◐Partially SupportedThe increased risk of atrial fibrillation (AFib) with high-dose omega-3s (4 grams) was not statistically significant at lower doses (800mg) in the VITAL trial.

◐Partially SupportedHigh consumers of fish and seafood may face health risks from heavy metals like cadmium, mercury, and lead.

✕Not SupportedFish oil should not be given to children; instead, they should consume healthy fats from meat and organs.

◐Partially SupportedIodine can be obtained from meat, dairy, and egg yolks, negating the need for fish as an iodine source.

✕Not SupportedRelying on fish or shellfish for dietary fats and proteins can lead to heavy metal accumulation.

◐Partially SupportedOptimizing the ratio of stearic acid to omega-6 fatty acids and avoiding seed oils is recommended for human health.

◐Partially SupportedMany in the health space advocate for high fish oil doses (4-8 grams per day).

◐Partially SupportedLow palmitic acid levels may be a marker for insulin resistance.

◐Partially SupportedDietary recommendations should be ideal but not impossibly restrictive.

◐Partially SupportedFat from meat and organs, such as heart, is a healthy source of fat for humans.

◐Partially SupportedShellfish can sometimes contain even higher levels of heavy metals than fish because they are bottom-dwelling organisms.

✕Not SupportedHigh doses of omega-3 fatty acids (EPA and DHA) from fish oil supplements are not associated with a reduced risk of major cardiovascular endpoints compared to corn oil or mineral oil.
